K2651-1 - Magnum PRO 250 Semiautomatic MIG Gun, 10 ft Cable

Precision, Durability, and Comfort in One Package

The Lincoln Electric K2651-1 Magnum PRO 250 Welding Gun is a premium 10-foot MIG torch designed to withstand the toughest welding environments while delivering precision results. Rated for 250 amps at a full 100% duty cycle using both CO2 and mixed gases, this gun is built for high-amperage applications where heat resistance is key. It is part of the Lincoln PRO Select Gun Selection System, which encourages welders to choose their equipment based on actual welding amperage and application needs rather than just machine ratings, ensuring you have the right tool for the specific job at hand.

Maintenance and serviceability are streamlined with the Magnum PRO series. The gun features a patent-pending Anti-Seize tip and diffuser thread design, which dramatically reduces the likelihood of parts fusing together due to heat and spatter. This feature alone saves countless hours of frustration and maintenance time. Additionally, the gun cable retention system creates a positive bond that resists pulling apart, a common failure point in lesser welding guns. Should field repair be necessary, the standard four-trigger lead configuration simplifies the process, getting you back to welding faster.

Versatility is a core strength of the K2651-1. It supports a wire size range from 0.035 inches to 5/64 inches, making it suitable for a wide array of material thicknesses and welding processes, including standard MIG and Flux-Cored welding. The simplified expendable parts selection is a major logistical advantage for shops with multiple machines; consumables for the 250A and 350A models are interchangeable with 450A and 550A models, reducing inventory complexity. Included with the unit are a contact tip, a 0.625-inch thread-on gas nozzle, and a thread-on diffuser, providing everything needed to connect and start welding immediately.
